Control components

• Mechanisms• Electrical/electronics• Used as part of control systems in products and

manufacturing industry

Input Process Output

Mechanical Components

Bevel gearsChain & Sprocket Worm & Worm WheelCrank

Cam & Follower

Spur Gears

• Make tasks easier• Generate some kind of force

and movement• Change direction and/or force

Electronic Components

• Individual components are built up into circuits

• Integrated circuits (ICs) have replaced many components

• Some ICs can be programmed and are called PICs

Composites

• Composites are made up from different materials to create new materials with improved properties

• Most material groups have composites

Composites

• Often very advanced materials (carbon fibre, Kevlar in resin)

• Very light but strong• Allow complex forms to be made

Standard components

Electrical Plug

Screws

Spark Plug

Zip Fastener

Resistors

• Ready-made standard components can be found in many products

• It is usually cheaper to manufacture these in large quantities in specialist factories rather than for each manufacturer to make their own

• Repairs are much easier when standard components are used
